DELIVERY-REEL FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented Dec. 26, 1916.

Application filed March 2, 1914. Serial No. 821,985.

To all whom it may concern:

Be it known that I, MARK J. GAnnIcK, a citizen of the United States of America, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Delivery- Reels for Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V

This invention relates to improvements in delivery reels for printing presses, and more particularly to such reels on the so-called stop cylinder press having a reciprocatory bed carrying the type, and its object is to provide the delivery reel with mechanism whereby the paper will, after being removed from the cylinder, be carried to such a position that its lower edge will be re moved from proximity to the type to prevent its engagement therewith on the return stroke of the bed; to provide a device which will accomplish this function positively and in a simple manner, and to provide the same with certain new and useful features hereinafter more fully described and particularly pointed out in the claim, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of that part of a printing press to which the mechanism embodied in this invention is applied; Fig. 2 is a sectional elevation showing the cylinder, bed, and delivery reel, and parts coacting therewith, with the frame of the machine removed, showing the bed at the end of its printing stroke and the cylinder, deliveryreel and paper in the respective positions they would attain at this point in the operation; Fig. 3 illustrates the same parts as Fig. 2, showing the delivery reel rotated sufficiently to carry the lower edge of the paper away from the type on the bed; Fig. 4: is a detail of the hub of the gear, which drives the delivery reel and shaft, illustrating the connection between the said gear and shaft; Fig. 5 is a transverse section on the line 55 ofFig. 1; and Fig. 6 is a detail of a portion of the delivery reel, showing the operation of the safety trip stops which operate the grippers thereon.

Like numbers refer to like parts in all of the figures.

1 represents the frame of a printing press, on which is journaled in boxes 2, the shaft 3 of the cylinder 4, said cylinder extending transversely across the frame.

5 is the bed of the machine, which is reder, from which the paper is fed sheet by sheet to the grippers 10 on the cylinder, which seize the paper at the beginning of the printing stroke and carry it upon the cylinder throughout a portion of its revolution and after printing releases the paper, which is then seized by the grippers 11 on the delivery reel 12 adjacent the cylinder, which remove the paper from the cylinder and carry it to the delivery fingers 13, from which it is taken by the fly 14 and ejected from the machine.

This invention is particularly adapted to be used in connection with so-called stop cylinder presses, in which the cylinder rotates during the printing stroke of the bed 5 and then stops and remains stationary during the return or idle stroke of the said bed during which time the paper which has been partially removed from the cylinder by the delivery reel also remains stationary. Heretofore as such machines have been constructed the lower edge of the paper is left in such a position that dining the return stroke it would be engaged by the type and the ink thereon would be wiped off upon the edge of the paper, thus resulting in a smutty job. The position of these parts and the paper in the position they would ordinarily stand during the return stroke of the bed, is illustrated in Fig. 2. In this machine, as is usual in this type of printing press, the delivery reel is driven by means of a gear 15 fixed tothe shaft 3 of the cylinder which meshes with a gear 16 connected to the shaft 18 of the delivery reel, but in this invention the connection between the gear 16 and the shaft 18 is not a rigid connection as is ordinarily the case, but consists of a collar 19 rigidly connected to the shaft preferably by means of a taper pin 20, and provided in its periphery with a recess 21, the ends of which form stop shoulders. The

gear 16 is loosely mounted on the shaft 18 adjacent the collar 19 and a pin 22 fixed in its hub extends into the recess 21 and engages the ends thereof. Thus when the gear 16 is rotated by means of the gear 15, the pin 22 engages one end of the recess 21 and rotates the shaft 18 and delivery reel 12 at the same speed as the cylinder, but when the cylinder stops, also stopping the gears 15 and 16, the momentum attained by the delivery reel will cause it to continue its rotation until the pin 22 has traversed the recess 21 and engages the opposite end there- 'of, thus causing the shaft and delivery reel to stop. This slack motion of the delivery reel is sufiicient to carry the lower edge of the paper above the type on the bed and free from contact therewith, as illustrated in Fig. 3. The bed may now return without danger of inking the lower edge of the paper, and when the parts again begin their printing movement the gear 16 will be rotated, carrying the pin 22 to the opposite end of the recess 21 where it will again rotate the shaft 18 and delivery reel 12.

To prevent undesirable movement of the shaft 18 and delivery reel 12, a friction brake 23 engages a brake drum 24 fixed to the shaft 18, the said brake 23 being of any suitable form to offer a slight resistance to the rotation of the shaft, and prevent its movement except when positively operated.

The grippers 11 upon the delivery reel 12 are mounted on a shaft 25 carried by the reel, which shaft is provided at one end with a trip lever 26. The grippers are normally held in gripping position by a suitable spring (not shown) coiled about the shaft or otherwise applied. The trip lever 26 engages, at certain positions during the revolution of the delivery reel 12, fixed stops 27, which cause the shaft 25 to oscillate, opening the grippers to either release or receive the edge of the paper 8. In this device the stops are projections 27 on arms 28 pivoted to a fixed portion of the machine and provided with stops 29 which engage the said fixed portion to prevent the arms moving when engaged by the trip lever 26, when the delivery reel is rotating in the operative direction. The arms 28 are yieldably retained in this normal position by means of springs 80. It is often desirable and necessary, when getting the machine ready for operation, that the reels be rotated in the reverse direction and with the steps 27 mounted on the pivoted arms 28 when the reel 12 is rotated in the reverse direction, the arms 28 when engaged by the trip lever, will rotate about their pivot as shown in Fig. 6, and permit the trip lever to pass by without doing damage.

WVhat I claim is In a printing press, a. frame, a shaft j ournaled in the frame, a cylinder mounted on the shaft, a second shaft rotatably mounted in the frame, parallel with the aforesaid shaft, a delivery reel fixed on the second shaft, a reciprocatory bed beneath the cylinder and reel, a gear fixed on the cylinder shaft, a gear loosely mounted on the delivery reel shaft and meshing with the aforesaid gear and including a hub, a relatively small collar fixed on the delivery reel shaft adjacent the hub of said loosely mounted gear and whose periphery is provided with a recess forming shoulders, a pin projecting laterally .from the hub of the gear on the delivery reel shaft and extending into the recess of said collar to ride thereon between said shoulders and engaging the latter alter nately whereby the momentum attained by the delivery reel shaft and the delivery reel will rotate the same a part of a revolution as said gears have stopped, and whereby said shoulders of the collar will arrest the inde pendent revolution of the delivery reel and its shaft,

In testimony whereof I affix my signature in presence of two witnesses.
